First post, so go easy on me... ;)

I'm having a strange issue with a class derived from DataObject and a SimpleTreeDropdownField. Here's the code:

class HomePage extends Page {
  static $has_many = array(
    'Spotlights' => 'Spotlight'
  function getCMSFields() {
    $fields = parent::getCMSFields();
    $fields->addFieldToTab('Root.Content.Focus', new DataObjectManager(
      array('LinkID' => 'Linked Page', 'LinkImageID' => 'Link Image'),
    return $fields;

class Spotlight extends DataObject {
  static $has_one = array(
    'Link' => 'SiteTree',
    'LinkImage' => 'Image'
  function getCMSFields_forPopup() {
    return new FieldSet(
      new SimpleTreeDropdownField('LinkID', 'Page to link to', 'SiteTree'),
      new ImageField('LinkImage', 'Link image')

I get the DataObjectManager in the CMS back-end, but when I try to add an entry, I do not get the SimpleTreeDropdownField. If I change 'LinkID' to 'Link' in the SimpleTreeDropdownField call the control shows up but anything I select does not get saved to the DB (obviously).

What am I doing wrong?

I'm using SS 2.4.0.
